Application filed May 21, 19211.

This invention relates to water faucets for use more especially with wash basins or the like.

The object of the invention, generally, is the perfecting ci faucets ot this cl'iaracter to render the same more eiiicient, durable, and less liable to der-alignment than those hitherto in use. l

More specific objects are to provide a basin faucet having a fluid pressure controlled, noisless, slow closing valve.

Still `other objects and advantages or the invention will appear' in the following specilication.

The invention consists in the improved construction, adaptation, and combination of parts hereinafter described and clain'ied.

In the accompanying drawing,"

Figure 1 is a side elevation, and Fig. 2 is a vertical central section oi a faucet embodying my invention.

The body of the i'aucet comprises a lower chambered member 5 and an upper chambered member 6. rl'Che lower member 5 has at its lower end a nipple element Z adapted to be connected to a water supply pipe.

The upper end of the said lower member extends into a socket or' the upper member and with which the lower member is coupled by interengaging screw threads, as shownv The member 5 is bored as at 8 and 9 to receive the ends 'of a cylindrical shell 10, herein after designated as the cylinder. Positioned in the bore 8 below the cylinder is a screen 11 of wire gauze, preferably, and a disk 12. Above the cylinder in the bore 9 is a disk 13 and above the latter is placed a gasket 14 to provide a watertight joint between the two body members.

15 represents a relatively small waterinlet opening into a cavity provided below the screen 11, and 16 represents restricted openings in the dish 12 affording communication between a cavity above said screen and the bore 17 of the cylinder 10. 18 represents a valve, preierably conical, which is adapted to close against a seat provided at the lower end -o'lf a port 19 extending` between the cylinder bore 17 and a relatively large chamber provided in the body part 6. The valve 18 is provided with a stem 21 extending above the valve and a plunger element 22 extending below the valve. A bored hub element 23 or the `disk 12 serves as a. guide for the valve plunger 22, and the port 19 serves as a guide for the stem Serial No. 714,762.

21 which extends above said chamber 2O.v Y

To permit water passing through the port 19 the valve stem 21 is tinted longitudinally as shown. Mounted on the stein 22 below said valve is a piston 24 having a diameter to fit within the bore oi the cylinder 10. Small apertures such as 25 are `provided in the pistonr to permit the passage of water therethrough..

The pressure of water acting against the lower end of the valve plunger 22 serves to normally retain the valve in position to prevent any flow yof water into the chamber 20.

To open the valve, the saine is manually pressed downwardly from its seat through the medium of a push rod 26 passing through a stuffing box 27 and having at its upper end a head 28. 29 represents a spout through which water is discl'iarged from the chamber 20, said spout being located so as to drain all water from the chamber there by obviating danger of freezing in cold weather.

The operation of the above explained parts is as follows: The operator pushing down upon the head 28 imparts downward motion to the push rod 26 which, in turn, acts upon the stem 21 of the valve 18 to effect the removal of the latter from its seat. When this occurs the water escapes from the chamber 17 through exit holes 25 and port 19 into the chamber 20 whence it is delivered through the nozzle 29. When the operator releases the head 28 the momentum of the water passing through the cylinder andthe direct pressure 'of water acting against the lower end of the plunger 22 serve to elevate the valve into its port closing position shown in Fig. 2.

The pressure of the water in the cylinder bore above the piston acting against the latter in the ultimate closing movement of the valve iinpedes the valve and eliminates any slam or noise. The closing movement of the valve, moreover, is retarded because of the relatively small or restricted sizes of the apertures 16 and 25 through which the water is compelled to travel into and from the space below the piston in the cylinder bore.V Y

In practice, the sum of the areas of the apertures 16 may be made greater or less than the sum of the areas of the apertures 25 in the piston 2a according to the water pressure obtaining in the service pipe, the

port into the rapidity at which the valve is desired to close, and also to the desired maximum flow of Water from the nozzle when the valve is fully opened with respect to the port 19.

The cylinder bore 17 constitutes, in etl'ect, a pressure reducing` chamber dne to the stricted sizes of the inlet openings 1j and also with respect to the outlet or port 19 considered with reference to the restricted sizes of the apertures 25 in the piston which functions as a movable partition.

The relatively large chamber' 20, furthermore, tends to ensure a steady delivery of water through the faucet spout when in operation.

In the present invention the peripheral wall` or shell 10 of the cylinder imperforate thereby causing all of the water which is 4delivered from the faucet to lirstV pass through the piston aprtures 25.

The employment ot a strainer in the faucet is of importancein sections of the country where the Water supply contains more or less impurities, sediment, etc.

What l claim, is,-

In a faucet having a body formed of two hollow members disposed, one above the other and separably connected together, a disk provided with a port affording communication between the chambers ol the respective body members, a valve 'for said port, a stem and a plunger element extending` from the valve and disposed respectively above and below the latter, said stem being guided by said port, a second disk provided with a bored boss element, said plunger lit ting within the bore ot' said boss, a cylinder' having an imperiiorated peripheral wall interposed between said disks and maintaining the same in spaced apart relations with each other, a piston operating in the cylinder and movable withsaid valve, apertures provided in the second named dish andk in said piston respectively to provide water inlets and exits for the space below the piston within said cylinder, a spout outlet for the upper of said body members, and means extending into said body for 'effecting thev opening movement ot' the valve with respect tocsaid port.
